The purpose of this work is to indicate the ways in which art and left-wing politics expressed themselves duirng the “long decade”. Avant-garde and revolution worked then as the art main thrust. The extensive repertoire of artistic manifestations reveals that from the encounter of these two concepts diverse and somtimes opposing poetics and artisitc-political programmes arised. The metaphors, although most dissimilar, overlap and mix up with each other in the same subjects in a vertiginous way. In spite of their diversity, they are united by the common understanding of the art as being capable of infl uencing the human life. There are plentiful of war metaphors: the art is perceived as activating and detonating power. The text proposes possible interpretations of the links between the art and the politics in the period of time investigated.
